Patent GB-554988-A (GB)
Title: Improvements relating to the finishing of textile fabrics
IPC: D06M15/39
Filed: 1942-01-29
Abstract: 554,988. Treating textiles with liquids &c. ; resinous condensation products. CALICO PRINTERS' ASSOCIATION, Ltd., and INGHAM, J. S. Jan. 29, 1942, No. 1246. [Classes 2 (iii) and 15 (ii)] A cellulosic textile fabric is filled and stiffened by applying to the fabric a stable watersoluble precondensate, prepared from formaldehyde and a ketone in the presence of an alkaline catalyst, applying sodium or potassium hydroxide solution to the fabric before or after application of the pre-condensate, and heating to form an insoluble resin in the fabric. The resulting stiffening and filling is resistant to washing with water, acids, and alkalies, and does not discolour on exposure to light. In preparing the precondensate a hydroxide of an alkali or alkaline earth metal or a carbonate of an alkali metal or a tertiary aliphatic amine may be used as alkaline catalyst. Preferably there should be not less than two molecular equivalents of formaldehyde to one of ketone. Any alkali remaining in the pre-condensate should be neutralized before concentrating the solution by evaporation where this step is required. A more concentrated solution may be obtained by using paraformaldehyde instead of an aqueous solution of formaldehyde. The ketone used may be acetone, or a keto-alcohol such as diacetone alcohol. In an example, a cotton fabric is impregnated with caustic soda solution, squeezed, impregnated with a syrup comprising a water soluble precondensate of formaldehyde and acetone, squeezed, and dried on hot cylinders. It is then washed and dried. The material is rendered stiff and springy. In another example, caustic soda solution thickened with seaweed extract is applied uniformly by a printing machine to a. cotton fabric impregnated with the precondensate. The fabric is dried at 100‹C., washed and dried. In another example an open weave. cotton fabric is treated with caustic soda solution and then with a condensation product of diacetone alcohol and formaldehyde. The fabric is dried and heated. The Provisional Specification refers also to the use of condensation products of formaldehyde with other aldehydes.

Abstract: 509,423. Eddy-current brakes; electromagnets. SHEVLIN, J. T. (List, H.). Jan. 14, 1@38, No. 1351. [Class 103 (i)] [Also in Group XXXV] An eddy-current brake for use as a speedregulating device comprises a hollow eddycurrent member axially adjustable with respect to the magnet, the field of which traverses the member radially and in at least a part of the iron circuit is saturated whereby a high degree of accuracy is obtained. In Figs. 1, 2 the magnet comprises a core 3 and a pair of limbs 1 provided with pole pieces 3a, 1a between which the metal eddy-current cylinder 5 rotates, the gap between the pole pieces being widened at the parts 4a so as to produce the necessary asymmetrical distribution of the field. To enable the degree of penetration of the cylinder 5 into the gap and thus the braking action and speed to be adjusted the cylinder pivot 5a is supported on a rod 7 slidable in the core 3 and adjustable by a lever 8 acting against a spring 7a. The cylinder is coupled to the mechanism to be controlled by the pinion 9. To eliminate temperature error, the cylinder 5 may be made of constantan or if it is made of copper a temperature-responsive device such as a bimetallic strip may be disposed between the lever 8 and rod 7 or the lever 8 may incorporate such a strip. A cylindrical member may be substituted for the limbs 1. In Figs. 4, 5, the magnet comprises a core 22 and four limbs 21, the poles being formed by the upper ends 21a of the limbs and by radial pins 22a received in recesses on the core. The poles extend into an insulating disc 23 and an iron ring 25 which may either be fixed or be carried by the eddy-current cylinder 20 completes the flux path. Adjustment of the cylinder 20 is effected by turning an eccentric disc 26 against which the pivot 2a is urged by a spring or by gravity.

Abstract: 707,431. Overhead railways. CLARKE ELLARD ENGINEERING CO., Ltd., and CLARKE, A. H. Jan. 19, 1953 [Jan. 17, 1952], No. 1365/52. Class 104 (2) A safety mechanism in which a carriage is prevented from over-riding the end of either of two relatively movable runways A, B except when the other runway is in a position to receive it has a cam 16 coupled to a movable stop 13 mounted on one runway and a cam-follower 17 coupled to a movable stop 13 mounted on the other runway actuated by mutual engagement when the two runways are brought into alignment so as to actuate the stops and allow a carriage to pass from one runway to the other. The cam 16 and the camfollower 17 are attached to plungers 6 slidable in guides 5 provided with rollers 7. The stops 13 are carried by a cross-piece slidably movable in slots formed in the webs 10 of the runways A, B the sides of which slots have wear plates 15 welded thereto. A bell crank 8 pivotally mounted on a pivot 9 on each runway A, B has an arm 8b which engages a recess 12 formed in the stop 13 and an arm 8a which projects through clearance holes in the runway top flange 3, a base-plate 4 and the plunger 6 to engage fork in a dog 11 mounted in the plunger 6, but slidable thereon against the action of a spring 19 to provide for lost motion. In the normal position the stops 13 fall by gravity into the block position on the lower flanges of the runways and as the runways are moved into alignment the cam-follower 17 rides up an inclined surface 16a of the cam 16 to lift through the bell cranks 8 the stops 13. The stops 13 are fully raised before the cam-follower 17 reaches the apex of the cam surface 16 and any subsequent outward movement is taken up by the lost motion between the plungers 6 and dogs 11. The cam-follower 17 is pressed by the springs 19 into a recess 18 formed in the apex of cam 16 when the runways A, B are aligned. The dog 11 may be fixed on one plunger 6 and the spring 19 dispensed with.

Abstract: 739,242. Friction shock-absorbers. RITZ, A., GAUDIN, C., and SECHAUD, R. F. Jan. 18, 1954 [Aug. 8, 1953], No. 1515/54. Class 108 (3). The invention relates to a shock-absorber of the type comprising a drum 3 co-operating with brake shoes 4, 5 each pivotally mounted at one end 6, 7 to a flange 1, a shoe-spacing member 8 being inserted between the other ends of the shoes, the spacing member 8 being controlled by a cam 3a angularly rigid with the drum 3. According to the invention, the member 8 is rigid with at least one arm 13 to one end of which is secured a coil-spring 14 connected at its other end to the end of a lever 15, pivotally connected to the flange 1. Furthermore a lever 16a pivoted to the lever 15 and carrying a roller 19 in engagement with the cam 3a, is acted on by a screw 21 carried by the lever 15. The screw 21 may alternatively be carried by the lever 16a and act on the lever 15. In the construction shown, there are two arms 13 both rigid with the member 8, two springs 14, and two mutuallyrigid levers 15. The shoes 4, 5 are each of U-shape in cross-section and carry at their free end, a pin 10 which bears on a lug rigid with the spacing member 8. In operation, when the attachment flange 1 and an arm 3b rigid with the drum 3, are in their normal relative position, the roller 19 rests in a recess 22 of the cam 3a. When relative movement occurs between the arm 3b and the attachment flange 1, the roller 19 rides up on the cam 3a and acts through lever 16a, levers 15, springs 14 and arms 13, to deflect the spacing member 8. The latter acts to move the shoes 4, 5 outwardly about their pivots 6, 7.

Title: Carburettors for internal-combustion engines
IPC: F02M59/02
Filed: 1933-01-17
Abstract: 407,167. Spray carburetters. DODSON, E., 16, Lewin Road, Streatham, London. Jan. 17, 1933, No. 1522. [Class 7 (iii).] A throttle-actuated accelerating fuel-pump has two resiliently -connected pumping elements such that when the throttle is rapidly opened and maintained open, one element instantaneously and temporarily supplies additional fuel whilst the other continues to supply additional fuel for a predetermined period. A cylindrical bore in the carburetter receives a plunger 11 connected by linkage 12, 13 to the throttle valve spindle 14. With slow throttle movement, fuel escapes through an aperture in the plunger, but on quick movement this aperture is closed by a valve 17 and fuel is forced past a valve 15 into a passage 16 and thence to the main mixture passage. An enlarged extension of the bore accommodates a plunger 18, a compression spring 19 being inserted between the two plungers. After movement of plunger 11 ceases, the compressed spring 19 forces down plunger 18 causing prolonged injection of fuel through valve 20 and constriction 21 to passage 16. Re-charging with fuel takes place from above through valves 17, 22. A rod 23 fast on plunger 11 slides in plunger 18 and has a head 24 to ensure positive return of the lower plunger when the throttle is closed. In a modification, the valve 22 is replaced by a valve in the base of the lower chamber to which fuel is fed by an external passage. In a further modification, the smaller plunger slides in a bore in the larger plunger, the same pumping chamber being common to both. The loading spring is outside a tubular extension of the smaller plunger and bears against a flange thereon. The valves 15, 20 and 17, 22 of Fig. 1 are, in this modification, combined respectively in a single valve.
